Patients with posttraumatic stress disorder (PTSD) exhibit smaller regional brain volumes in commonly reported regions including the amygdala and hippocampus, regions associated with fear and memory processing. In the current study, we have conducted a voxel-based morphometry (VBM) meta-analysis using whole-brain statistical maps with neuroimaging data from the ENIGMA-PGC PTSD working group.
Methods
T1-weighted structural neuroimaging scans from 36 cohorts (PTSD n = 1309; controls n = 2198) were processed using a standardized VBM pipeline (ENIGMA-VBM tool). We meta-analyzed the resulting statistical maps for voxel-wise differences in gray matter (GM) and white matter (WM) volumes between PTSD patients and controls, performed subgroup analyses considering the trauma exposure of the controls, and examined associations between regional brain volumes and clinical variables including PTSD (CAPS-4/5, PCL-5) and depression severity (BDI-II, PHQ-9).
Results
PTSD patients exhibited smaller GM volumes across the frontal and temporal lobes, and cerebellum, with the most significant effect in the left cerebellum (Hedges’ g = 0.22, pcorrected = .001), and smaller cerebellar WM volume (peak Hedges’ g = 0.14, pcorrected = .008). We observed similar regional differences when comparing patients to trauma-exposed controls, suggesting these structural abnormalities may be specific to PTSD. Regression analyses revealed PTSD severity was negatively associated with GM volumes within the cerebellum (pcorrected = .003), while depression severity was negatively associated with GM volumes within the cerebellum and superior frontal gyrus in patients (pcorrected = .001).
Conclusions
PTSD patients exhibited widespread, regional differences in brain volumes where greater regional deficits appeared to reflect more severe symptoms. Our findings add to the growing literature implicating the cerebellum in PTSD psychopathology.
National policy in England recommends that young people be admitted to mental health wards that are age-appropriate. Despite this, young people continue to be admitted to adult wards.
Aims
To explore the impact of young people’s admissions to adult wards, from the perspectives of young people, parents/carers and mental health professionals working in adult services.
Method
Semi-structured interviews were conducted with 29 participants to explore experiences of receiving and delivering care in adult mental health wards. Participants were four young people (aged 16–17 years), four parents/carers and 21 mental health professionals from adult mental health services in England. Data were analysed using framework analysis.
Results
Young people’s admissions to adult wards tend to occur out of hours, at a time of crisis and when no suitable adolescent bed is available. Admissions were conceptualised as a short-term safety measure rather than for any therapeutic input. Concerns were raised about safeguarding, limited treatment options and a lack of education provision for young people on adult wards. However, exceptionally, for older adolescents, an adult ward might be clinically or socially appropriate. Recommendations to reduce adult ward admissions included better integration of adolescent and adult services, having more flexible policies and increasing community provision.
Conclusions
Our findings emphasise the importance of young people being admitted to age-appropriate in-patient facilities. Earlier intervention and increased provision of specialist care in the community could prevent young people’s admissions to adult wards.
Limited access to multiple sclerosis (MS)-focused care in rural areas can decrease the quality of life in individuals living with MS while influencing both physical and mental health.
Methods:
The objectives of this research were to compare demographic and clinical outcomes in participants with MS who reside within urban, semi-urban and rural settings within Newfoundland and Labrador. All participants were assessed by an MS neurologist, and data collection included participants’ clinical history, date of diagnosis, disease-modifying therapy (DMT) use, measures of disability, fatigue, pain, heat sensitivity, depression, anxiety and disease activity.
Results:
Overall, no demographic differences were observed between rural and urban areas. Furthermore, the categorization of primary residence did not demonstrate any differences in physical disability or indicators of disease activity. A significantly higher percentage of participants were prescribed platform or high-efficacy DMTs in semi-urban areas; a higher percentage of participants in urban and rural areas were prescribed moderate-efficacy DMTs. Compared to depression, anxiety was more prevalent within the entire cohort. Comparable levels of anxiety were measured across all areas, yet individuals in rural settings experienced greater levels of depression. Individuals living with MS in either an urban or rural setting demonstrated clinical similarities, which were relatively equally managed by DMTs.
Conclusion:
Despite greater levels of depression in rural areas, the results of this study highlight that an overall comparable level and continuity of care is provided to individuals living with MS within rural and urban Newfoundland and Labrador.
To determine and compare the intraoperative durability of 4 major surgical glove brands.
Design, Setting, and Participants:
This study is a randomized open-label clinical trial in which surgical gloves from 4 manufacturers are randomized to 5 surgical subspecialty study groups: (1) orthopedic surgery, (2) neurosurgery, (3) colorectal surgery, (4) trauma or acute general surgery, and (5) cardiac and plastic surgeries. The study was divided into 10 periods, with a cross-over design, and was conducted at a tertiary care academic medical center. Participants were licensed and certified physicians, physicians-in-training, scrub nurses, or technicians working within the sterile field.
Interventions:
Participants from each study group were randomly assigned to 1 of 4 surgical glove manufacturer types and subsequently rotated through the other 3 glove brands such that each participant acted as their own control in the sequential cross-over design.
Main Outcomes and Measures:
The primary outcome was to determine and compare the intraoperative failure rate of Biogel® Sterile Surgical undergloves against sterile surgical undergloves from 3 other manufacturers, both as a combined competitor group and individually.
Results:
There were no differences between brands with respect to the primary outcome of underglove intraoperative failures. Brand 1 wearers were slightly more likely to detect glove failures when they occurred.
Conclusion:
The durability of surgical gloves intraoperatively is similar across 4 major glove manufacturers. Detection of intraoperative failures is infrequent, though specific glove characteristics may promote enhanced detection. Recognition of glove perforations intraoperatively is important in the maintenance of a maximally sterile field.
Multisector stakeholders, including, community-based organizations, health systems, researchers, policymakers, and commerce, increasingly seek to address health inequities that persist due to structural racism. They require accessible tools to visualize and quantify the prevalence of social drivers of health (SDOH) and correlate them with health to facilitate dialog and action. We developed and deployed a web-based data visualization platform to make health and SDOH data available to the community. We conducted interviews and focus groups among end users of the platform to establish needs and desired platform functionality. The platform displays curated SDOH and de-identified and aggregated local electronic health record data. The resulting Social, Environmental, and Equity Drivers (SEED) Health Atlas integrates SDOH data across multiple constructs, including socioeconomic status, environmental pollution, and built environment. Aggregated health prevalence data on multiple conditions can be visualized in interactive maps. Data can be visualized and downloaded without coding knowledge. Visualizations facilitate an understanding of community health priorities and local health inequities. SEED could facilitate future discussions on improving community health and health equity. SEED provides a promising tool that members of the community and researchers may use in their efforts to improve health equity.
OBJECTIVES/GOALS: 1. Standardize pathways, training and evaluations 2. Expose apprentices to a variety of research experiences 3. Remove barriers to hiring early talent 4. Expand opportunities for underrepresented minority applicants to obtain clinical research professional positions METHODS/STUDY POPULATION: Collaborators connected by the Clinical Research Professional Taskforce ACTS SIG conducted a landscape analysis survey to identify aspects of CRP Apprentice models and formed a Subgroup. Members will share plans for multiple apprenticeship programs, including specific training modalities and skill sets used to prepare apprentices for a successful clinical research professional career. Methods across institutions include: • Increasing awareness of the profession • Facilitating talent identification for managers • Making the business case for funding and staffing • Implementing work-based learning for fundamental competency development Survey results from CRP institutions demonstrated apprenticeships are value added to teaching how to conduct research. RESULTS/ANTICIPATED RESULTS: The landscape survey of Apprentice programs revealed multiple models in use. The newly formed Apprentice subgroup is engaging in analysis and actively working to build a standardized repository of competency-aligned, research courses and experiences for apprentices. Results will help make the business case for starting or growing programs. Subgroup members have focused on a shared goal of expanding opportunities for underrepresented minority applicants, with current outreach efforts that are extending awareness of the CRP profession. We anticipate a continuous strengthening of connections between institutions to share a variety of models to implement, develop shared tools (e.g., proficiency tests), and share existing tools to standardize pathways and training for CRP apprenticeships. #_msoanchor_1 DISCUSSION/SIGNIFICANCE: Academic Medical Centers (AMCs) need novel strategies to support clinical research portfolios.Innovative Apprenticeship Models improve efficiency and sustainability of the clinical research professional (CRP) workforce to train the next generation of CRPs in an effective and timely way.
Guided CBT self-help represents a low-intensity intervention to deliver evidence-based psychological therapy within the Improving Access to Psychological Therapies (IAPT) programme. Best practice guidance highlighting characteristics associated with CBT self-help is available to help services reach decisions regarding which interventions to adopt. However, at present a single process to evaluate written CBT self-help interventions informed by guidance is lacking. This study reports on the development of a standardised criteria-driven process that can be used to determine the extent written CBT self-help interventions are consistent with guidance regarding the fundamental characteristics of low-intensity CBT and high-quality written patient information. Following development, the process was piloted on 51 IAPT services, with 23 interventions identified as representing free-to-use written CBT self-help interventions. Overall, inter-rater reliability was acceptable. Following application of the criteria framework, 14 (61%) were considered suitable to be recommended for use within the IAPT programme. This pilot supports the development and potential utility of an independent criteria-driven process to appraise the suitability of written workbook-based CBT self-help interventions for use within the IAPT programme.
Key learning aims
(1) To recognise the range of written low-intensity CBT self-help interventions currently used within IAPT services.
(2) To identify separate criteria associated with high-quality written CBT self-help interventions.
(3) To use identified criteria to develop a framework to evaluate written workbook based low-intensity CBT self-help interventions for use within the IAPT programme.
(4) To evaluate inter-rater reliability of the criteria framework to evaluate the quality and appropriateness of written workbook based low-intensity CBT self-help interventions used within IAPT services.
We undertake the first quantitative and broadly comparative study of the structure and performance of partnership communities to our knowledge. Our study addresses several important research questions. How connected are the members of partnership communities? How can we understand the quality of the projects a community undertakes? How do political institutions shape their structure and performance? After defining partnership communities as networked communities of private firms which form the consortia that enter into long-term contractual arrangements with governments, we show how they are affected by government demand for partners. We then provide an overview of those factors predicting success in financing projects. Finally, we focus on the political economy of partnership communities. We develop and test theoretical predictions about how national institutions shape partnership communities and the quality of projects. We also investigate voters' preferences over alternative arrangements of infrastructure delivery before drawing out implications for research and practice.
Background: Carbapenem-resistant Enterobacteriaceae (CRE) are endemic in the Chicago region. We assessed the regional impact of a CRE control intervention targeting high-prevalence facilities; that is, long-term acute-care hospitals (LTACHs) and ventilator-capable skilled nursing facilities (vSNFs). Methods: In July 2017, an academic–public health partnership launched a regional CRE prevention bundle: (1) identifying patient CRE status by querying Illinois’ XDRO registry and periodic point-prevalence surveys reported to public health, (2) cohorting or private rooms with contact precautions for CRE patients, (3) combining hand hygiene adherence, monitoring with general infection control education, and guidance by project coordinators and public health, and (4) daily chlorhexidine gluconate (CHG) bathing. Informed by epidemiology and modeling, we targeted LTACHs and vSNFs in a 13-mile radius from the coordinating center. Illinois mandates CRE reporting to the XDRO registry, which can also be manually queried or generate automated alerts to facilitate interfacility communication. The regional intervention promoted increased automation of alerts to hospitals. The prespecified primary outcome was incident clinical CRE culture reported to the XDRO registry in Cook County by month, analyzed by segmented regression modeling. A secondary outcome was colonization prevalence measured by serial point-prevalence surveys for carbapenemase-producing organism colonization in LTACHs and vSNFs. Results: All eligible LTACHs (n = 6) and vSNFs (n = 9) participated in the intervention. One vSNF declined CHG bathing. vSNFs that implemented CHG bathing typically bathed residents 2–3 times per week instead of daily. Overall, there were significant gaps in infection control practices, especially in vSNFs. Also, 75 Illinois hospitals adopted automated alerts (56 during the intervention period). Mean CRE incidence in Cook County decreased from 59.0 cases per month during baseline to 40.6 cases per month during intervention (P < .001). In a segmented regression model, there was an average reduction of 10.56 cases per month during the 24-month intervention period (P = .02) (Fig. 1), and an estimated 253 incident CRE cases were averted. Mean CRE incidence also decreased among the stratum of vSNF/LTACH intervention facilities (P = .03). However, evidence of ongoing CRE transmission, particularly in vSNFs, persisted, and CRE colonization prevalence remained high at intervention facilities (Table 1). Conclusions: A resource-intensive public health regional CRE intervention was implemented that included enhanced interfacility communication and targeted infection prevention. There was a significant decline in incident CRE clinical cases in Cook County, despite high persistent CRE colonization prevalence in intervention facilities. vSNFs, where understaffing or underresourcing were common and lengths of stay range from months to years, had a major prevalence challenge, underscoring the need for aggressive infection control improvements in these facilities.

OBJECTIVES/GOALS: Irreproducible and incompletely reported research lead to misallocated resources, wasted effort in pursing inappropriate avenues of investigation, and loss of public trust. To address this challenge, we employed a Team Science approach to create a multi-modal program to support Rigor, Reproducibility, and Reporting in Translational Science. METHODS/STUDY POPULATION: We conducted literature searches to reveal sources of irreproducibility and recommended corrective actions, invited leaders in the field to give lectures on opportunities to support reproducible science, and worked with the Rockefeller team science leadership group to instill an overarching rigor approach, infused into all training efforts. This multifaceted program was labeled R3 (R-cubed) for Enhancing Scientific Rigor, Reproducibility, and Reporting. RESULTS/ANTICIPATED RESULTS: Didactic Courses:
Introduction to Biostatistics and Critical Thinking – focus on pitfalls in inferential statistics, consequences of poor research, and errors in published research.
Scientific Writing – teaches methods and procedures in writing to ensure reproducibility. Lecture Series
Established nine lectures on topics related to R3, including Data Management, Statistical Methods, Genomic Analyses, Data Repositories, Data Sharing, Pharmacy Formulation, and e-lab notebooks. Website
Creating a comprehensive website as repository for research, methods, programs, updates, and improvements related to R3. KL2 Clinical Scholars Seminars and Navigation
Scholars participate in seminars and tutorials to discuss opportunities to improve R3 across the research life-course.
DISCUSSION/SIGNIFICANCE OF IMPACT: Striving for research reproducibility takes focused energy, discipline, and vigilance, but the effort is worthwhile as rigorous and reproducible science is the prerequisite for successful translation of great discoveries into improved health.

Psychosocial stressors deriving from socioeconomic disadvantages in adolescents can result in higher metabolic syndrome (MetS) risk. We aimed to examine whether socioeconomic disadvantages were associated with MetS independent of lifestyle and whether there was a dose response relationship between the number of cumulated socioeconomic disadvantages and the risk of MetS.
Materials and Methods:
The present study included 1,037 European adolescents (aged 12.5–17.5) of the 3,528 total HELENA participants. Sociodemographic variables and lifestyle were assessed through self-reported questionnaires. Disadvantaged groups included adolescents with low educated parents, low family affluence, migrant origin, unemployed parents, and from non-traditional families. MetS score was calculated as the sum of sex- and age-specific z-scores of waist circumference, HOMA-IR index, mean of z-scores of diastolic and systolic blood pressure and mean of z-score of HDL-C multiplied by -1 and z-score of TG. A higher score indicates poor metabolic health. Linear mixed-effects models were used to study the association between social disadvantages and MetS risk score. Models were adjusted for sex, age, pubertal status (Tanner stage) and lifestyle (diet quality, physical activity, alcohol consumption and smoking status).
Results:
Adolescents with low educated mothers showed a higher MetS score (0.54 [0.09–0.98]; β [99% confidence interval]) compared to high-educated mothers. Adolescents who accumulated more than three disadvantages (0.69 [0.08–1.31]) or with missing information on disadvantages (0.72 [0.04–1.40]) had a higher MetS risk compared to non-socioeconomically disadvantaged groups. Stronger associations between socioeconomic disadvantages and MetS were found in male in comparison with female adolescents.
Discussion:
Out of the studied socioeconomic disadvantages, maternal education is the most important determinant of adolescent's MetS risk independently of sex, age, Tanner stage, smoking status, alcohol consumption, diet quality and physical activity. Social vulnerabilities (migrant background, unemployment status and belonging to a non-traditional family) were not associated with a higher MetS risk in European adolescents. However, we found a dose-response relationship between the number of factors related to social disadvantage and adolescents’ MetS risk with adolescents accumulating three or more socioeconomic disadvantages showing the highest risk. Stronger associations between socioeconomic disadvantages and MetS were found in male compared to female adolescents. Policy makers should focus on low educated families to tackle health disparities.
This paper synthesises the data and results of the Konya Regional Archaeological Survey Project (2016–2020) in order to address the earliest evidence for cities and states on the Konya and Karaman plains, central Turkey. A nested and integrative approach is developed that draws on a wide range of spatially extensive datasets to outline meaningful trends in settlement, water management and regional defensive systems during the Bronze and Iron Ages. The significance of the regional centre of Türkmen-Karahöyük for a reconstruction of early state polities between the 13th and eighth centuries BCE is addressed. In light of this regional analysis, it is tentatively suggested that, during the Late Bronze Age, Türkmen-Karahöyük was the location of the city of Tarḫuntašša, briefly the Hittite capital during the reign of Muwatalli II. More assuredly, based on the analysis of the newly discovered Middle Iron Age TÜRKMEN-KARAHÖYÜK 1 inscription, it is proposed that Türkmen-Karahöyük was the seat of a kingdom during the eighth century BCE that likely encompassed the Konya and Karaman plains.
This paper examines the misalignment between modern human society and certain male phenotypes, a misalignment that has been highlighted and explored in great detail in the work of Tom Dishion. We begin by briefly enumerating the ongoing developmental difficulties of many boys and young men and how these difficulties affect them and those around them. We then suggest that the qualities that have been advantageous for men and their families in our earlier evolution but that are often no longer functional in modern society are a source of these problems. Finally, we provide a brief review of prevention programs that can contribute to preventing this type of problematic development and eliciting more prosocial behavior from at-risk boys and men. We conclude with an overview of research and policy priorities that could contribute to reducing the proportion of boys and young men who experience developmental difficulties in making their way in the world.
This study examines the potential health-related impact of recent versus lifetime experiences of sexual orientation discrimination among older Australian lesbian women and gay men. In a nationwide survey, a sample of 243 lesbian women and 513 gay men aged 60 years and over reported on their experiences of sexual orientation discrimination and their mental and physical health, including psychological distress, positive mental health and self-rated health. Among both lesbian women and gay men, recent discrimination uniquely predicted lower positive mental health after adjusting for experiences of discrimination across the lifetime and socio-demographic variables. In addition, recent discrimination uniquely predicted higher psychological distress among gay men. Experiences of discrimination over the lifetime further predicted higher psychological distress and poorer self-rated health among gay men after adjusting for recent experiences of discrimination and socio-demographic variables. However, there were no associations between lifetime discrimination and any of the outcome variables among lesbian women. Overall, recent and lifetime experiences of sexual orientation discrimination were related to mental and physical health in different ways, especially among the men. These findings have potential implications for policy/practice, and suggest that distinguishing between recent and lifetime experiences of discrimination may be useful when assessing potential health-related impacts of sexual orientation discrimination among older lesbian women and gay men, while also taking account of differences between these two groups.
Wildlife is an essential component of all ecosystems. Most places in the globe do not have local, timely information on which species are present or how their populations are changing. With the arrival of new technologies, camera traps have become a popular way to collect wildlife data. However, data collection has increased at a much faster rate than the development of tools to manage, process and analyse these data. Without these tools, wildlife managers and other stakeholders have little information to effectively manage, understand and monitor wildlife populations. We identify four barriers that are hindering the widespread use of camera trap data for conservation. We propose specific solutions to remove these barriers integrated in a modern technology platform called Wildlife Insights. We present an architecture for this platform and describe its main components. We recognize and discuss the potential risks of publishing shared biodiversity data and a framework to mitigate those risks. Finally, we discuss a strategy to ensure platforms like Wildlife Insights are sustainable and have an enduring impact on the conservation of wildlife.
Microstructural analysis and bulk dielectric property analysis (real and imaginary permittivity at 95 GHz) were performed at temperatures ranging from 25 to 550 °C for ceramic composites comprising a hot-pressed aluminum nitride matrix (containing yttria and trace carbon as sintering additives) with molybdenum powder as a millimeter-wave radiation-absorbing additive. Loading percentages in the range of 0.25 vol% to 4.0 vol% Mo were characterized. For the temperature regime evaluated, the temperature-related changes in real and imaginary components of permittivity were found to be relatively modest compared with those driven by Mo loading. Energy-dispersive X-ray spectroscopic analysis of Mo grains and surrounding regions showed the presence of a mixed-phase layer, containing Mo2C, at the AlN–Mo interface. The Mo2C-containing mixed-phase layer, typically a few micrometers thick, surrounded the Mo grains. Further characterization of this mixed-phase layer is required to determine its contribution to the dielectric properties of the composite.
To investigate whether adherence to the adapted Mediterranean Diet Score for Adolescents (MDS_A) and the adapted Mediterranean Diet Quality Index for Adolescents (KIDMED_A) is associated with better food/nutrient intakes and nutritional biomarkers.
Design:
The Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study is a cross-sectional study aiming to obtain comparable data on a variety of nutritional and health-related parameters in European adolescents aged 12·5–17·5 years.
Setting:
Nine European countries.
Participants:
European adolescents (n 2330) recruited to the HELENA study. Dietary intake was obtained with 24 h dietary recalls, an FFQ and a Food Choices and Preferences questionnaire. MDS_A was calculated as a categorical variable using cut-offs (MDS_A), as a continuous variable (zMDS_A) and with energy adjustments (zEnMDS_A). The KIDMED_A score was also calculated.
Results:
Multilevel linear regression analysis showed positive associations for zMDS_A and KIDMED_A with serum levels of vitamin D, vitamin C, plasma folate, holo-transcobalamin, β-carotene and n-3 fatty acids, while negative associations were observed with trans-fatty acid serum levels. For categorical indices, blood biomarkers showed few significant results. zMDS_A and KIDMED_A showed positive associations with vegetables and fruits intake, and negative associations with energy-dense and low-nutritious foods. zMDS_A and KIDMED_A were positively associated with all macronutrients, vitamins and minerals (all P < 0·0001), except with monosaccharides and PUFA for KIDMED_A and cholesterol for both indices (P < 0·05).
Conclusions:
zMDS_A and KIDMED_A have shown the strongest associations with the dietary indicators and biomarkers that have been associated with the Mediterranean diet before, and are therefore considered the most appropriate and valid Mediterranean diet scores for European adolescents.
Aboriginal children in Australia are over-represented in both the child protection and juvenile justice systems. Using Western therapeutic models of practice with Aboriginal people who live in remote communities can be highly problematic. Moreover, the historical legacy of past and present legislation, government interventions and racist service provision needs to be acknowledged and addressed prior to any service implementation. This paper presents a therapeutic model of practice that incorporates Aboriginal concepts of healing and spirit within a creative therapeutic framework. It will demonstrate how the model works through principles of community engagement and capacity building, enabling the provision of a culturally derived therapeutic intervention that involves a synergy of both Aboriginal- and Western-based healing practices. The findings from the implementation of the TeaH model affirm the need to incorporate Aboriginal concepts of healing, spirit and creative therapies into mainstream practice with Aboriginal people.
